The 26-year-old has not featured in a Brazil squad for more than two years, but Hiddink has denied the loan represents a gamble for Chelsea.

"Coming on loan makes it possible to have a good view on him, and on whether he is able to adapt to the high demands of the club and the league," the interim manager said. "It is a brave step. It's up to him."

Cahill has lost his regular starting place to Kurt Zouma in recent weeks but Hiddink, who spoke to the England centre-half this week, said: "There was no hint from his side 'can I leave the club?' Nothing.

"First he's very happy. He's of value and, as far as I'm concerned, I will have him in the upcoming months and I think the club will have him in the upcoming years."
